<br>Hi Sarah,<br><br>You may want to try the same filters that are used for correcting <br>for MRI intensity inhomogeneity.<br><br>See the directory:<br>InsightApplications/MRIBiasCorrection<br><br>These classes approximate the illumination distribution with a <br>
polynomial, and then use the polynomial in order to normalize<br>the intensity across space.<br><br>You may also find useful the following paper of the Insight Journal:<br><br>"N4ITK: Nick's N3 ITK Implementation For MRI Bias Field Correction"<div class="authors">

<div>Hi,</div>
<div>I'm new to ITK. I have a series of brain images taken with a camera that when combined are supposed to form a 3 dimensional volume. The camera had a flash and the slices don't all have the same lighting and shadowing effects. Does anyone have any suggestions how to correct this so that all the images have the same light distribution?</div>
<div>Thanks,</div>
<div>Sarah</div></td></tr></tbody></table><font color="#888888"><br>
